摘　　要：为探讨不同提取方式对藤椒油脂肪酸组成成份的影响,本研究采用冷榨法、植物油浸提法和有机溶剂浸提法提取鲜藤椒果实所含的油脂,并用气相色谱-质谱(GC/MS)法对不同藤椒油中脂肪酸的组成成分和相对含量进行分析。结果表明:从3种藤椒油中共鉴定出17种脂肪酸,其中共同含有的脂肪酸有8种。不同工艺提取的藤椒油脂肪酸组成和相对含量存在一定差异,冷榨油和热浸油中脂肪酸以油酸相对含量最高,分别为57.91%和59.93%;溶剂浸出油中脂肪酸以棕榈油酸为主,相对含量高达45.55%。3种藤椒油中富含不饱和脂肪酸,均高于84%,且单不饱和脂肪酸相对含量远高于多不饱和脂肪酸,不同提取方式间无显著差异;多不饱和脂肪酸均以亚油酸和亚麻酸为主。本研究为藤椒油的提取和开发利用提供了依据。The objectives of the present work were to investigate the effect of different extraction methods on the relative contents and compositions of fatty acids in Zanthoxylum armature DC. Prodr. oil, and three methods were adopted, including cold pressing, vegetable oil extraction and organic solvent extraction. And their fatty acids analyses were performed by GC-MS. A total of 17 fatty acids were identified in these three kinds of oil, among which, 8 fatty acids were detected simultaneously. It indicated that significant differences and similarities in the relative contents and compositions were observed among the samples. Oleic acid was shown to be the main constituent in the oil obtained by cold pressing and vegetable oil extraction, with the relative contents of 57.91% and 59.93% , respectively. While 9- Hexadecenoic acid was the dominant constituent in the oil extracted by organic solvent extracted oil, and the relative content was up to 45.55%. The total content of unsaturated fatty acids in all samples was more than 84% , among which, monounsaturated fatty acids were predominant group of constituents and there were no significant differences between different extraction methods. In addition, the major polyunsaturated fatty acids were linoleic acid and linolenic acid. The result of this study can provide a theoretical basis for the extraction and exploration of Zanthoxylum armature DC. Prodr. oil.
